To all whom t may concern: j

Be it known that I, ALBERT E. TABER, a

citizen of the United States, residing at" Great- My invention relates to improvements in feed-water heaters; and its novelty, utility,

no and practical advantages will be fullyunderstood from the following description and `claims when taken in conjunction withthe accompanying drawings, in which- Figure l is an elevation, partlyfinsection,

x of the left side `of so much of a'locomotiveboiler as is necessary to illustrate my invention; Fig. 2, a similar view of the right side of the boiler; Fig. 3, a transverse section taken in the plane indicated by the broken line 3 3 2o ofFig. 1; Fig.` Afan enlarged detail section.

illustrating the arrangement of the pipes for supporting and supplying my improved combined water-boxand baiiie in the fire-box of the boiler; Fig.` 5, an elevation of the com-e` z 5 bined water-box and baiiie which I prefer to employ; Fig. 6, an end elevation of the same Fig. 7 a vertical transverse section taken in the plane indicated by the broken line 7 7 of Fig. 5, and Fig. 8 a horizontal transverse section taken in the plane indicated bythe broken line 8 8 of Fig. 5.

Referring by letter to the said drawings,`

and more particularly to Figs. 1 toethereof, A is a locomotive-boiler havingthe p. usual 5 lire-'box a and water-leg b, and Bis the combined water-box and baffle of my improvements. This box B, which is constructed of steel, in such manner as to enable it to withstand great pressure, is disposed in the iire- 4o box at about the angle of inclination shown in Fig. l, so as to adapt it to serve the purpose of the ordinary bafiie-plate andv at the same time present it to the direct action of the ire. It is supported in position by pipes or rods C andpipes D D', which are screwed into its ends and extend through transverse sleeves c, fixed in the walls of the water-legs, and is also supported by pipes E, which connectits upper portionV with the water-space of the 5o boiler. From the bottom of said water-box I prefer to extend a pipe d, equipped with a blow-0E e., as illustrated. j

F is an injector arranged to be supplied with steam from the boiler and with water from the locomotive tender or any other source of supply; G, a pipe connecting the injector and the pipe D and provided with a check or non-return valve H, arranged to seat in a direction away from the water-box B; I, a pipe connecting the pipe D and the lower portion of the water-leg b and also having a check or n on-return valve I-I, arranged to seat in a direction away from the box B, and K a pipedisposed, by preference, at the left side of the boiler and between the pipe D and the upper portion of the water-space of the boiler and provided with a check or non-return valve H2, arranged, like the valves H H, to seat in a direction away from the box B.

In practice when steam is let into the injector F and the same is,` operating to force water past valve H and through pipe G, pipe D, water-box B, and pipes E into theboiler the valves I-I H2 are held against their seats and communication between the box B and the boiler through pipes I and II is closed. When, however, steam is cut 0E from the in-` jector and the same ceases to force feed-water to be heated through the box B, the valve II seats and closes communication between the boiler andthe injectonwhilethe valves H H2 open under Athe weight of the water and `permit the water to circulate from the lower and upper portions of the boiler through pipes I and K, pipes DD', thewater-box B, and pipes E back into the boiler. This circula- 'tion of the water through the box B while the injector is idle not only assists in making It will be appreciated from the foregoing that by virtue of my improvements 'the feedwater is thoroughly heated precedent to entering the boiler, and while the injector is idle a circulation of water through the boiler and box B is maintained, as is desirable.

While I prefer to employ the pipes D and K and the valve H2, I do not desire to be understood as limiting myself to the same, as they may be omitted without destroying the operativeness oi' my improvements. In the steam, but precludes burning out of the box B.

IOO

event of the pipe D being dispensed with a plugged pipe or rod, such as C, will be employed to assist in supporting and holding the box B in position.

The combined water-box and baiiie of my improvements may be of the construction shown in Figs. 1 and 4 and indicated by B or of any other construction calculated to withstand great pressure without departure from the scope of my invention. I prefer, however, to have the combined water-box and bafiie embody the construction shown in Figs. 5 to 8 and indicated by B. This latter construction, Figs. 5 to S, comprises a i'lat plate m, of steel, which forms a portion of the uppermost side wall of the box and baffle; a steel plate n, which forms the lowermost side wall of the box and is bent,as indicated by p and o", to form the bottom and top walls, respectively, of the box and is provided in said bottom and top walls with apertures s t.

and also in the wall p by preference with a washout-aperture u, normally closed by a plug c; interiorly-threaded pipe-sockets s t',

which surround the apertures s t, respectively, and have iianges connected by rivets to the walls p and r; steel plates w, which form the end walls of the box and have iianges 0c, arranged at the inner sides of and connected by rivets to the walls m, n, p, and fr, and also have apertures y and reinforcing-plates y',

connected by rivets to their inner sides and provided with threaded apertures y2, coincident with the apertures gj; rivets z, which con= nect thc lapped edges of the plates m n, and transverse stay-bolts a', which are interposed between and connect the upper and lower sides of the box. The pipe-socket s/ is designed for the connection of the pipe d, Figs. l to 3, the pipe-sockets t for the connection of the pipes E, and the threaded apertures y2 in the reinforcing-plates y for the connection o-f the supports and pipes C, D, and D'.

It will be appreciated from the foregoing that by reason of the construction of the combined water-box and baiiie B a continuous plate n, free from seams, is presented to the direct action of the iire,which contributes materially to the durability of the box and baffle also, that the combined water-box and baffle B as a whole is exceedingly strong, and hence calculated towithstand for a long period the great pressure to which such devices are ordinarily subjected.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to suc-l1 speciiic construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims.

Having described my invention, what I claim, and desire to secure by Letters Patent,
